Crazy voltages - Page 2

post #11 of 13
The Molex will tell tales if you get a nice reading out of it. If you do short out the psu it will deff go boom, At least when it doesn't has a seperate fuse.
But again...don't measure voltages when attached to the mobo. A short circuit will totally ruin your rig. Detach everything when measuring it. If you are still in doubt try a old Psu and connect only the bare necesseties (hope i got that word right) lol

Ok, I'll try this when my new motherboard arrives and I have to take the thing apart anyway

Last time I blew up a PSU was 1995, it was pretty loud

Ok, I tested the psu with nothing plugged into it and pins 15 and 16 bridged and this is what I got.

1) Do these voltages look right?

2) Should pin 20 be completely missing from the cable like this? It's missing on both sides of the 24pin cable but the motherboard and psu both have a pin on them.

Code:
4 Pin molex:
5.16V
12.35V

24 Pin ATX2:
